On FullSailed we have and do cook underway. The gimballed stove is a great convenience while cooking as it greatly reduces sloshing induced not just by heel but that caused by confused seas and wakes. Our stove will rock about 30* on either tack and will bottom out against the hull on port tack. If your stove is already mounted swing it untill it bottoms on the hull and then measure the angle. If the angle is less than 30* consider if the swivel point can be brought inboard. If not, then keep this in mind when cooking and/or considering the conditions to cook in. From my own experience, about 20 years ago, I found myself on a mooring outside of Avalon Harbor at Catalina Island. I was cold and wet. The wind was 20-30 kts on the port bow with wind waves/chop about 2 feet. The Catalina 38 was rolling at least 20* or more, but, The Admiral cooked a hot meal on a gimballed (alchohol) stove. There is more to the story, but later.
